AIR SAMPLING SYSTEMS
When do you need to know there is a fire?
When high value assets, equipment or irreplaceable items are at stake, early warning of a smoke or fire problem, is essential. Our air sampling or air monitoring equipment actively pulls in room air to a special chamber where it can detect the presence of particles that are created in the very early stages of combustion, even before smoke is visible. With the world’s widest sensitivity range, VESDA air monitoring produces multi-level warnings at the very early stage of an impending fire. This provides the valuable time necessary to initiate a flexible, appropriate response.
VESDA detection for Computer Rooms
VESDA detection is ideal for area that have high airflow. Conventional smoke detectors struggle to activate with high amounts of air passing through their chambers. VESDA detectors draw smoke from the aspirating pipe and the holes in the pipe collectively capture the air and draw it back to the VESDA detector. VESDA smoke detection is far more responsive than conventional smoke detectors.
VESDA detection for Fire Suppression Applications
VESDA detection with Fire Suppression is a fantastic combination. With ever increasing environmental responsibilities, it is essential that a fire suppression system should deploy unnecessarily. VESDA smoke detection use in conjunction with conventional smoke detection is a perfect match. Preferably VESDA detection samples the air across the return plenums of the air conditioning systems which provide primary smoke detection! An alert alarm can be raised and human intervention can prevent the gas from discharging!
VESDA detection for Warehouses
VESDA smoke detection is a suitable replacement for conventional smoke detection where accessibility is limited. For example, VESDA detection will be better suited to a warehouse with smoke detectors situated at high levels. Conventional smoke detectors can become faulty and access equipment will need to be deployed, this can be extremely disruptive to operation and it is also dangerous. VESDA smoke detection eliminates this issue as the aspirating pipe work will be located at high levels and the VESDA detector will be located at accessible levels. Aspirating pipe will replace the smoke detectors at high level, with holes in the aspirating pipe replacing the smoke detectors.
VESDA detection for Cold Storage
VESDA smoke detection is commonly used where temperatures are not suitable for other types of smoke detection. For example, a cold room operating temperatures ranging from -4°F to 40° F, is an ideal environment for VESDA smoke detection. Cold temperatures will ice up the optical chambers of conventional smoke detectors rendering the system useless. VESDA detectors are located outside the cold environment, with aspirating pipe work located within the risk or outside the risk with capillary smoke sampling heads located within the risk! The cold air is then drawn to the VESDA smoke detector and is naturally heated before it arrives at the VESDA laser chamber. The condensation is collected at a condensate water trap and dry air arrives for sampling by the VESDA detector. In extreme cases air dryers may be needed, but in the most, are not required for the VESDA system!
Where VERY early detection of smoke is an absolute necessity. . . there is no substitute for aspirating air sampling detection. The VESDA line of air sampling detectors is the most widely specified, installed, and has a proven track record of reliability.
